The numbers you show on your fingers are Bullwinkle’s antlers.
 * Bullwinkle The Moose Math**

__Activity: Show me. . .__ Show me. . . a number up to ten. Ask the students to show you the same number in a different way too. (Say the number or hold up a card with the numeral written on it.)

__Extensions__ Show me. . . put two students (moose) together and have them show you any number up to 20 without talking. They can just look at each others antlers. Show me. . . put three students (moose) together and have them show you any number up to 30 without talking. They can just look at each others antlers. Have two moose stand back-to-back (so that they can not see each others antlers) and put up as many fingers up as their antlers as they wish. A third student says the sum of the antlers. Each moose has to say the number that the other moose has up in their antlers.

__Activity Variations__

Instead of identifying or showing a certain number on the antlers. Have students show: One more? One less? Two more? Two less? The double? The double plus one more? How many more does it take to make 10? etc.
